Lineup help for a 1-4 team that needs a win!

I’m sitting at 1-4 in my league and am struggling to make a decision on my starters this week. My QB Aand WR’s are set, but my RB’s and Flex are giving me trouble.

QB Matt Ryan
WR Julio Jones (start), Thielen (start), John Brown
RB Hyde, Morris, Collins, Ekeler, D. Cook, Powell, P. Lindsay

I’m leaning towards Hyde and Cook (assuming he plays) with Powell in the flex. Any suggestions?
